Title: Improvements in automatic adjustment means for brake mechanisms
IPC: F16D65/52
Filed: 1954-06-29
Abstract: 739,577. Brake adjustment devices. SHEPHERD, G. H. June 29, 1954, No. 19093/54. Class 103 (1). Automatic adjustment mechanism for shoedrum brakes comprises stop members e irreversibly screwed into a threaded housing f and caused by a torsion spring g to follow up the movement of the shoes as they are spread apart by the actuator BC. The members e are, however, kept spaced away from the surfaces l on the shoes by the distance n as a result of detents h urged outwardly by springs i of greater thrust than the spring g. When the shoes are retracted the stop members e remain fixed but the detents h are pressed back against springs i so that the shoe clearance is set at the distance n. In the embodiment shown in Fig. 2, the stop members e thrust against the shoes through Belleville washers q, the washers being compressed on the release of the brakes to give the clearance n. In Fig. 5, a snail cam m is rotatably urged by a coil spring g so as to maintain contact with a detent lever n. On release the lever n is pivoted so as to compress spring i through a distance that may be adjusted by the setting of cam l, the principle of action being thus similar with the cam m replacing the members e.

Title: Improvements in and relating to copying devices for machine tools
IPC: B23B51/10
Filed: 1962-05-18
Abstract: 973,516. Copying lathes. SZERSZAMGEPFEJIESZTO INTEZET. May 18, 1962 [Nov. 14, 1961], No.19213/62. Heading B3T. A tracing device for machine tools such as lathes whereby two machining operations may be effected on one workpiece, from a single master template comprises, a main tracing member 8 which is rotatable about a pivot 13 and one end of which rests against a master template 10. The main tracing member carries an auxiliary tracing member 7 which is rotatable relative to the main member about a pivot 9. One end of the auxiliary member is urged against a set--screw 6 by a spring 5, the other end engaging an hydraulic copying piston 11 which is attached to a carriage 2 with a cutting tool 4. During a first machining operation the two tracing members move as one unit, as in Fig. 1, tracing the form of the template 10 which is reproduced on the workpiece 3. To perform the second operation, solenoid 12 is operated which moves the auxiliary tracer 7 about pivot 9 against the spring 5 to permit the edge of the main tracer to contact the piston 11 (see Fig. 2) which effects movement of the tool carriage 2 towards the work, the other end of the main tracer remaining in contact with the template. A second machining position is thus obtained. The difference in cuts between the two machining positions is proportional to the difference in end positions of the two tracing members which is determined by set-screw 6.

Title: Improvements in a method of applying brake lining
IPC: B21D53/34
Filed: 1930-06-25
Abstract: 358,002. Brake linings. FORD MOTOR CO., Ltd., 88, Regent Street, London. June 25, 1930, No. 19394. Convention date, Aug. 10, 1929. [Class 103 (i).] A method of attaching the lining to brake shoes or other brake members consists in clamping the brake member and the lining against a die shaped to correspond with that of the drum or other member with which the lining is to engage and securing the lining while so clamped. The lining is thus caused to fit closely to the brake member and the necessity for grinding the surface of the lining after attachment is avoided. A machine is described by which a brake shoe and lining may be forced against a cylindrical die under high hydraulic pressure and be then drilled and riveted. A cylinder 12 has attached to it a cylindrical die 15 to receive the brake lining and is pierced with an upper and a lower row of holes 22 corresponding to the rivet holes 20, Fig. 5, on either side of the web 17 of a T-section brake shoe. A plunger 13 working in the cylinder 12 has an arcuate slot 21 to receive the web 17. A series of anvils 23 for clinching the rivets are radially slidable into and out of position in the plunger 13 by links connecting them to a crank 25 on a shaft having a handle 27. A fixed piston 29 is arranged in a bore in the plunger 13. Brackets 38, 39 swingably mounted on trunnions 37 and a hydraulic plunger 36 carry respectively a riveting head 43 and an electric drill head 50. The head 43 has a piston 45 carrying a riveting shaft 48. The head 50 can be reciprocated by a rack-and-pinion and hand-lever 51. The hydraulic system comprises low, high and medium pressure pumps 55, 56, 57, driven by a motor 53, each with a relief valve 72, 73, 59 set at the desired pressure. In operation, the valve 77 is first set at position R so that pump 55 supplies through pipe 79 to the space between the piston 29 and the plunger 13 which is thus retracted to enable the brake shoe and lining to be fitted to the plunger and the die 15. The valve 77 is then moved to position 1 so that both pumps 55, 56 supply at the low pressure through pipe 80 to the cylinder 12 and by the channel 33 to the space between piston 29 and plunger 13 which is thus rapidly advanced to the outer position shown. The valve is then moved to position 2 for a short time so that only the high pressure pump 56 supplies to the pipe 80. The valve 62 being in the position shown so that the plunger 36 is in the lower position, the lower row of rivet holes are countersunk by swinging the bracket 39 and rivet head 50 into position adjacent the openings 22. The valve 62 is then positioned so that the pump 57 supplies to the cylinder of the plunger 36 which lifts the drill and riveting heads 50, 43 to permit first the drilling and then the riveting operation for the upper row of rivets. The plunger 36 is then lowered for fixing the lower row of rivets. The riveting operation is effected by supplying liquid from the pump 57 alternately to one side and the other of the piston 45 by the valve 65.

Filed: 1958-06-18
Abstract: 862,896. Adjusting body height. CLAYTON DEWANDRE CO. Ltd. June 15, 1959 [June 18, 1958], No. 19511/58. Class 108(2). A levelling valve for an air spring has an actuating beam 2 moved by an operating arm 4 through a crank-pin 7. The beam 2 operates inlet and exhaust valves 8, 9 by its end 2a and a plate 14. A rocking motion of the beam arm 2a will open one or other of the valves without actuating the other valve. A stem 15 pivoted by a pin 16 to the arm 2a moves one or other of pistons 17 when it is displaced from its mid position to damp hydraulically movement of the beam 2. The end 2b of the beam is held in its mid-position by a spring 32 via a stem 29 and a pin 30. When the suspension is in a static condition the beam 2 occupies a horizontal position. A slow movement of the operating arm 4 causes the crankpin 7 to rock the beam 2 about the pin 30, which is held stationary by the spring 32, to operate the appropriate valves 8 or 9. During this movement one of damper pistons 17 will be drawn towards the other, oil being displaced through a restricted orifice into a reservoir. On rapid movement of the operating lever the hydraulic damper will prevent movement of the beam arm 2a the beam pivoting about the pin 16 and the movement of the end 2b being accommodated by the spring 32. The degree of damping may be adjusted by a needle valve.

Abstract: 790,974. Electric digital-data-storage apparatus. NATIONAL CASH REGISTER CO. July 3, 1956 [July 5, 1955], No. 20544/56. Class 106 (1). [Also in Group XL (c)] A magnetic writing head 1 is driven in one sense or the other by a circuit including a P-N-P type junction transistor 3 and an N-P-N type junction transistor 4 having the winding of the head as a common load impedance and controlled by two-level voltage signals applied to points 7, 8. The latter are connected to voltage dividers 9, 10 arranged so that the control signals of + 100 or +125 v. produce, at the base of the transistor 3, +25 or +35 v. respectively and, at the base of the transistor 4, - 35 or - 25 v. respectively. The emitter electrodes of the transistors 3 and 4 are respectively connected to +30 and - 30 v. sources. Thus, when the lower voltage signal is applied at 7 and 8, transistor 3 conducts and electron flow takes place in the winding 1a in the direction 12 to write " zero," the transistor 4 being rendered non conducting. When the higher voltage signal is applied at 7 and 8 only transistor 4 conducts and the direction of electron flow in the winding la is reversed, as indicated at 14, to write " one ". If no signal is to be recorded, the higher and lower signals are applied to 7 and 8 respectively to render both transistors non-conducting. In this case, the collector electrode cut-off currents in the winding 1a cancel each other. Limiting resistors 5, 6 with by-pass condensers 13, 15 are provided.

The turbine wheel 18 of an hydraulic coupling is connected to an output shaft 20 by a ratchet clutch 19 comprising an intermediate ring 26 helically splined at 27, 28 to a hub 22 of the turbine wheel 18 and carrying clutch teeth 31 engageable with teeth 32 on the output shaft 20. Helical movement of the ring 26 to engage the teeth 31 synchronously with the teeth 32 is initiated by a pawl 33 engageable with the teeth 31. The clutch 19 may be held engaged for bi-directional drive by a piston 34 splined at 42 to the hub 22 and engageable with teeth 44 on the ring 26. The piston 34 is biased towards engagement with the teeth 44 by a spring 45 and is moved left against the bias of the spring 45 by supplying pressure liquid to a chamber 39. In a motor vehicle transmission system, Fig. 6, pressure liquid is supplied to the chamber 39 from a pump 52 through a valve 48 when a gear shift lever switch 56 is closed. The clutch 19 is thus normally held engaged for bidirectional drive by the piston 34 and is released for one way drive during ratio shift. A centrifugally controlled valve 57 vents the fluid coupling at engine idle. In Fig. 7 (not shown), a piston (60) acts on the intermediate ring (26) to disengage the clutch at engine idle. In Figs. 7 and 8 (not shown), the pawls (33) are carried by the intermediate ring and engage the teeth on the output shaft.
